A 525-ft-long sliding girder, originally built for a Hong Kong project, will place around 1,000 concrete elements of a 2.1-mile viaduct for a new high-speed railroad.
As the first anniversary of work on the U.K.’s 225-km London-Birmingham high-speed railroad (HS2) is reached, news of a major bentonite leak of more than 1,500 cu m at the project’s first tunnel has revived opposition to the project.
Robotic arms for tunnel-boring machines, concrete reinforcement made of old wind turbine blades and machine learning to reduce concrete waste are among innovations emerging from the $16.7-billion civil construction program for the U.K.’s London to Birmingham high-speed railroad. Construction began late last year.
A team of New Zealand-based software designers that brought digital 3D modeling to engineering geotechnics less than two years ago recently launched an upgrade to their software. It is now being used on some major projects, including the U.K.’s multibillion-dollar London-Birmingham high speed railroad (HS2).
The estimated $5-billion restoration of the 19-century landmark was approved in 2018, but the organization responsible for overseeing work was begun only in April.
